[0002] It is an object of the present invention to provide a self contained device for enabling a person to efficiently and effectively apply lotions to the back. Another object of the present invention is to provide a device which significantly improves upon all other lotion applicators by providing for a more efficient means to disburse lotions through the reservoir device and into the unique terry cloth covered, highly flexible and soft sponge which is currently being manufactured KIWI, INC. and is obtainable off the shelf. Still another object of the present invention is to provide a device that uses modern, plastic injection molding techniques to provide for easy to use and low cost manufacturing.

[0003] A contoured hand held, low pressure activated sun-screen dispenser & applicator for the back. It is designed for use with all suntan and lotion applications to the skin. Inducement force is delivered from a squeezebulb pump having a check valve at each end and communicating downstream to a threaded fitting which attaches and communicates to the interior of a hollow lightweight plastic reservoir for the storage of the specific product. At the opposite end of the pump is a terry cloth covered sponge which acts as the disbursement agent for the lotion(s). The entire unit is comprised of four (4) distinct components. 1, squeezebulb 2, contoured reservoir adapter 3, detachable hollow reservoir 4, terry cloth covered sponge which attaches to the reservoir via a slid locking mechanism for easy replacement and cleaning. The entire design is adapted for one person application of lotion to an individual's anatomical back.

[0004] The low pressure pump component consists of an inlet, ball check valve 1 of FIG. 1 and mounted in said inlet to admit ambient air into the squeezebulb. Another component is a tulip-style flutter, outlet check valve 2 of FIG. 1 being located at the opposite end of the squeezebulb to obstruct back flow, whereby consecutive squeezing and releasing of squeezebulb pumps bursts of inhaled air through said inlet to contoured reservoir adapter 3 of FIG. 2 and downstream through reservoir 5 of FIG. 3 into the sponge head component 6 of FIG. 4. The pump component attaches to the contoured reservoir adapter by either standard screw type connection or by standard snap style connection for easy assembly and disassembly. One of the principle features of the squeezebulb is it's small size and tough rubber flexibility which is best suited for one-handed use.

[0005] The contoured hollow reservoir adapter 3 of FIG. 2 consists of a contoured shape and design that is best suited for one handed use by incorporating a location for one's thumb for added stability. Additionally, the reservoir adapter contains a semi-flexible rubber flange that is molded into the adapter shaft located at the adapter's downstream screw-cap connection component 4 of FIG. 2. The rubber flange and screw-cap component attaches to the upstream end of the reservoir housing 4 b of FIG. 3.

[0006] The reservoir component FIG. 3 is consistent with the contoured shape of the reservoir adapter as to provide or the best suited design for applying lotion to an individual's back. Located at the downstream position of the reservoir is a molded flat flange unit 5 a FIG. 3 which communicates directly with the mounting features of the terry cloth covered sponge component FIG. 4. In the extreme downstream position of the reservoir flange unit are three (3) ⅛ inch holes that communicates to corresponding ⅛ inch holes located in the terry cloth covered sponge mounting bracket. The function of the holes are to allow lotion(s) to be pumped from the reservoir through the reservoirs extreme downstream position and out the three (3) ⅛ inch holes and into the terry cloth covered sponge unit for effective and efficient disbursement of lotion(s) to the skin, in particular the back.

[0007] The terry cloth covered sponge component 6 FIG. 4 is a commercially available product which is slightly modified by the attachment of the mounting bracket 6 a FIG. 4 for easy engage and disengagement of the sponge component. The sponge component directly communicates with the downstream reservoir flange unit. An inherit feature of the terry cloth covered sponge component is that when lotion(s) are pumped into the sponge the terry cloth material acts as a barrier for the lotion until applied to the skin. Therefore eliminating the need for a pressure activated valve within the sponge unit as described in U.S. Pat. No. 6,045,279 and significantly reducing the manufacturing costs.

BACKGROUND OF THE INVENTION

[0008] The invention is in the field of lotion dispensers and applicators, particularly to the pumping/delivering of lotion(s) through a hand held dispenser and into an applicator pad.

[0009] Almost all lotion applicators researched used a gravity method of delivering the lotion onto an applicator head or used a siphon device built into the applicator head to pull the lotion/substance onto the applicator. The utility design for the “Pump Sun-screen Lotion Dispenser & Applicator For The Back” as shown, improves upon all other previous designs by incorporating a bulb shaped pump handle for a more controlled method of forcing the lotion material/substance through the reservoir into the applicator head and onto the skin.

[0010] Unlike the patented lotion applicator U.S. Pat. No. 6,045,279 “Easy Reach Lotion Applicator” which uses a floating pressure plate within the applicator head to create positive pressure on the dispensed product. The Pump Sun-screen Lotion Applicator & Dispenser For The Back utilizes a patented sports ball pump as it's pump mechanism which is readily available off the shelf.

[0011] The field of search included 128/62 R,269,357,365,DIG.15 132/88.5,88.7. The pump classification researched included 417, 437,472,440 and U.S. Pat. No. 5,556,258 with the following U.S. Classifications: 417/63; 417/440; 417/478; 417/480. While researching existing lotion applicators it became apparent that no other design in any way incorporated a squeeze bulb style pumping device onto the dispenser.

SUMMARY OF THE INVENTION

[0021] The invention fulfills the above stated function of pumping lotion/substances through the uniquely designed handle and reservoir into the applicator pad. Very significantly, it is also adapted to one-handed operation which also makes it inherently valuable to the medical field for people who have trouble reaching certain parts of their body.

[0022] The “Pump Sun-screen Lotion Dispenser & Applicator For The Back” improves upon all other previous designs by incorporating a bulb shaped pump handle for a more controlled method of forcing the lotion material / substance through the reservoir into the applicator head and onto the skin.

[0023] The intuitive beliefs of the inventor is that this pump activated and uniquely shaped hand held lotion applicator will significantly increase the use of sun-screen protective lotion by people who overexpose themselves to dangerous levels of UV rays. And will become a popular tool for dermatologist who have patients who can not reach portions of their body for the application of medicated ointments or lotions.

DETAILED DESCRIPTION OF THE INVENTION

[0024] The invention is a contoured, self contained hand held, low pressure activated sun-screen dispenser & applicator for the back. The process of use involves the pouring of the lotion substance into the reservoir where the pump handle connects to the reservoir. After inserting the lotion substances into the reservoir the handle screws onto the reservoir which also holds the applicator pad. The invention is unique in its function and design by the way the pump handle communicates with the reservoir and applicator pad. The invention device is constructed of modern, plastic injection molding techniques to provide for easy to use and low cost manufacturing. Another principle feature of the invention is that it is durable and designed and assembled for ease of cleaning.

[0025] The operating mechanics of the invention causes inducement force to be delivered from a squeezebulb pump located at one end. The check valve at each end of the pump communicates downstream to a threaded fitting which attaches and communicates to the interior of a hollow lightweight plastic reservoir for the storage of the specific product. The low pressure pump component consists of an inlet, ball check valve and mounted in said inlet to admit ambient air into the squeezebulb.

[0026] At the opposite end of the pump is a cloth covered sponge applicator pad which acts as the disbursement agent for the lotion(s). The entire invention is comprised of four (4) distinct components. 1, squeezebulb 2, contoured reservoir adapter 3, detachable hollow reservoir 4, terry cloth covered sponge which attaches to the reservoir via a slid locking mechanism for easy replacement and cleaning. In the extreme downstream position of the reservoir flange unit are three (3) ⅛ inch holes that communicates to corresponding ⅛ inch holes located in the terry cloth covered sponge mounting bracket which acts as a barrier for the lotion until applied to the skin.

[0027] The contoured hollow reservoir adapter consists of a contoured shape and design that is best suited for one handed use by incorporating a location for one's thumb for added stability. The entire design and function is adapted for better one person application of lotion to an individual's anatomical back.
